Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed August 2, 1918. Serial No. 247,985.

To all whom it may concern:

Be it known that I, WILLIAM P. DEVINE, L citizen of the United States, residing at Dorchester, county of Suffolk, State of Mas- ;achusetts, have invented an Improvement .n Machines for Applying Covering Ma- ;erial to Articles, of which the following de- ;cription, in connection with the accomoanying drawing, is a specification, like :haracters on the drawing representing like carts.

This invention relates to machines for apolying covering material such as leather, extile material and materials of a similar :haracter to articles such, for example, as aye-glass cases, which machines may be of ;he general type disclosed in the patent to Brown No. 1,117,162 granted November 17 L914.

The object of the invention is to provide ior the operation of the wipers with which ;uch machines are provided in such a manier that ready access may be had by the perator to the space between the cooperatng dies.

A further object of the invention isto provide a rotary actuator in the bed plate for the wipers of the machine together with perative connections between the said ac- ;uator and wipers whereby the proper proecting and retracting movement of the wipers is effected by the rotary movement )f the actuator and in which preferably the orojecting rotary movement of the actuator f .llustrating the invention disclosedherein .n connection with a machine for applying covering material to eye-glass cases and nore-particularly to the cover of such cases. The shape of the article to. be covered,.the ahape of the necessary dies, the'particular neans for effecting the relative movement )f the dies, the number ofwipers employed,

the timing of themovement of the wipers, and various other features of the machine are not however specifically involved in the invention and may obviously be varied as desired to embody the invention subject to the requirements of the claims.

The machine illustrated for the purpose of disclosing a preferred form of the invention is particularly designed for applying covering material to the cover portion of eye-glass cases but is obviously readily .adaptableto applying covering material to various other articles. It comprises a supporting frame 1 which may be secured to' a .table or other support 2 by bolts 3 and which is provided with a horizontally projecting arm 4 and an overhanging arm 5.

The parts are then in the position substantially as shown in Fig. 4 and the covering material is firmly clamped and pressed against the article on the bottom surface and at the inturned edges. The handle lever is then elevated; the article removed and the operation repeated.

The wipers may be of any number and have their efiective edges shaped to correspond with the edge of the article to be cov ered. These Wipers may be of various construction but are herein shown as consisting of generally flat plates 11, 1'2, 13 and 14 sliding in the general radial direction in ways 4:4, 45, 46 and 47 respectively cut in the bed plate 6 and held in place by the cover plate 15. The wipers are given their projecting and retracting movements by an actuator rotatably mounted in the bed plate and which in the preferred form illustrated consists of a metal ring sector 48 rotatably mounted in an annular way 49 cut in the bed plate 6 concentric with its center. This rotary actuator 48 is operatively connected to the several wipers to secure the proper movements thereof either simultaneously or sequentially. For this purpose pin and cam slot connections are conveniently used and in the form shown the actuator is provided with upwardly projecting pins 50,51, 52 and 53 entering the cam slots 54, 55, 56 and 57 respectively. In Fig. 5 the actuator is shown as having been moved to bring the pins to the outer end of the cam slots and thus to have projected the wipers to their extreme inner position turning the edge of the covering material upon the article. When the actuator is moved in the opposite direction the wipers are simultaneously retracted. If the action of the wipers is to be a sequential one then a construction such as shown in Fig. 10 may be employed wherein the cam slots in the wipers are provided with concentric sections 58, 59, 60 and 61 respectively. These may be arranged to give the required sequence of action and in the construction shown are so arranged that the wipers 62 and 63 are first projected and then the wipers 64c and 65 are subsequently projected, the retracting movements taking placein inverse order.

Thus in either case upon rotation of the actuator in one direction projecting movement of the wipers is effected and upon rotation of the actuator in the opposite direction retraction of the wipers is effected.

The rotary movement of the actuator to effect the projection of the wipers is preferably secured by means movable with respect to the actuator and preferably by a means connected with the vertically movable die carrier while the rotary movement of the actuator to effect the retraction of the wipers is preferably secured, by a spring. A preferred construction for thus effecting the rotary movements of the actuator is illustrated.

The rotary actuator as has been noted is preferably a ring shaped sector 48. At one end of the sector the actuator is cored out and in the core is mounted a spring 66 and preferably a plunger 67 This spring acts through the plunger against an abutment 68 secured rigidly in place in the way 49 by a set screw 69. The spring thus interposed between the bed plate and the actuator normally acts to effect the rotary movement of the actuator which causes the retracting movement of the wipers. The rotary movement of the actuator which causes the projectin movement of the wipers is shown as secure d by a plunger 7 0 depending from aft vertical movable die carrier 8 and vertically adjustable therein by means of the nuts 71 on its screw threaded shank. This plunger carries a projecting cam 72 with an inclined lower face and the lower end of the plunger is steadied by riding into an aperture 73 in the bed plate. The adjacent end of the ring shaped sector constituting the rotary actuator 48 is provided with an opposed cam member 74 having an inclined upper face and this cam member 7 4 is preferably pivotally mounted at 75 in the actuator so as to swing upwardly. It will thus be seen that as the die carrier descends the plunger enters the aperture 7 3 and its cam 7 2 comes into contact with the cam 74 of the rotary actuator. The result is that the rotary actuator is cammed around in its way in opposition to the spring 66 and through the pin and slot connectlons acts to give the proper projecting movements to the wipers. The cam 72 of the plunger passes beneath the cam 7 4 and as the rotary actuator moves in the retracting direction before the dies separate the pivoting of the cam 74 enables the plunger to recede and in its receding movement swing the cam 7 4 upwardly. The cam 74 is normally brought to its operative position by gravity or. if required a spring 76 may assist in returning it to normal position.

It will thus be seen that this invention provides for an entirely free space or opening between the cocperating dies so that the operative may readily place the article to be covered in position and remove it when covered from between the dies. The plunger 7 0 is conveniently located at the rear or away from the operative as shown in the drawings leaving the entire space between the dies unobstructed. It will also be seen that the mechanism is of a simple construction, that the parts may readily be made strong and durable and subject to a minimum amount of wear, and that the operation of projecting and retracting the wipers is effectively.

Cir

and accurately controlled. All the parts are readily accessible for removal or repair when necessary.
